Tubing
� Tube retainer of the nut is made from a two-stage struc-ture, enabling it to hold the tubing firmly.
� Fitting’s seal surface to the tubing adopts a unique de-sign to the area’s pressure, resulting in improved sealing performance.

Collet
Protrusion� Strengthening the prevention of the tube release by
means of the collet structure.
� Sealing performance is highly maintained in a circumfer-ential seal surface having a unique shape even under thermal stress conditions.
Nut Body
� To establish the tightening position, a gauge control is not required as the nut is designed to be tightened until the end surface of the fitting’s main body.
Prevents the nut from loosening at a high tightening torque, and from installing in a tilted position.Heat resistant.
Providing additional strength against possible tube bend-ing or deformation

Applicable Fluids
The material and fluid compatibility check list provides reference values as a guide only.Note 1) Since static electricity may be generated, implement suitable countermeasures.Note 2) Use the nut material made of PFA because the nut material, PVDF can be used depending on the environment or temperature.
• Compatibility is indicated for fluid temperatures of 200°C or less (In the case of the nut material made of PVDF: 150°C or less)• The material and fluid compatibility check list provides reference values as a guide only, therefore we do not guarantee the application to our product.• The data above is based on the information presented by the material manufacturers.• SMC is not responsible for its accuracy and any damage happened because of this data.

1. Confirm the specifications.Give careful consideration to operating conditions such as the application, fluid and environment, and use within the operat-ing ranges specified in this catalog.
2. FluidOperate within the indicated fluid temperature range.
3. Maintenance spaceEnsure the necessary space for maintenance and inspections.
4. Fluid pressure rangeKeep the supplied fluid pressure within the operating pressure range shown in the catalog.
5. Countermeasures for static electricitySince static electricity may be generated depending on the flu-id being used, implement suitable countermeasures.
Design and Selection
Warning
1. After mounting, perform suitable function and leak tests to confirm that the mounting is correct.
2. Instruction manualMount and operate the product after reading the manual care-fully and understanding its contents. Also keep the manual where it can be referred to as necessary.
Mounting
Warning
Piping
Caution1. Connect tubing with special tools
Please refer to the LQ3 series mounting method in “High Puri-ty Fluoropolymer Fittings: Hyper Fittings/Flare Type” (M-E06-4) for tubing connection and special tools. (Downloadable from our web site.)
2. Tighten the nut until it touches the end surface of the body, and then tighten it an additional 1/8 turn. As a guide, refer to the proper tightening torques shown below.Also, when the nut requires extra tightening, please conduct this job in accordance with the instruction manual.

1. Perform maintenance in accordance with the proce-dures in the instruction manual.Improper handling can cause damage.
2. When removing or reinstalling fittings, remove any remaining chemicals and carefully replace them with deionized water or air, etc., before beginning work activities.
3. Tightening of taper threads for pipingBecause the taper threads are made of resin, minute leakage may gradually occur due to stress relaxation. Perform periodic inspections, and if leakage is detected correct the problem by additional tightening. If additional tightening becomes ineffec-tive, replace the fitting with a new product.
4. Check the following during regular maintenance, and replace components as necessary.a) Scratches, gouges, abrasion, corrosionb) Twisting, flattening or distortion of tubingc) Hardening, deterioration or softening of tubing
5. Do not repair or patch the replaced tubing or fittings for reuse.
Maintenance
Warning
1. Do not use in locations having an explosive atmos-phere.
2. Do not operate in locations where vibration or im-pact occurs.
3. In locations near heat sources, block off radiated heat.
Operating Environment
Warning1. Operate within the range of the maximum operating
pressure.
Operating Precautions
Warning
1. After a long period of non-use, perform inspections before beginning operation.
2. Use sufficient care in the handling of the LQ series clean packaging types when opening the package.
Caution
1. Refer to the applicable tubing sizes shown below for tubing to be used.
